The United States has illegally flown its high-altitude balloons over Chinese airspace more than 10 times without Chinese authorities' approval since the beginning of last year, Chinese Foreign Ministry spokesperson Wang Wenbin said on Monday.
It is not rare for U.S. balloons to enter the airspace of another country illegally, Wang told a regular press briefing in Beijing.
The U.S. has also frequently sent warships and aircraft to conduct close-in reconnaissance on China, which undermines China's sovereignty, he said.
The U.S. should change its way and do some soul-searching, instead of smearing or blaming the Chinese side, said Wang, in reference to Washington's recent claim about a Chinese "spy balloon."
The Chinese Foreign Ministry has repeatedly made clear that the entry of a Chinese civilian unmanned airship, which is for meteorological purposes, into U.S. airspace was due to force majeure and totally an accident.
